Definitions

  • the present invention relates to a modular unit for applying opening devices to packages of pourable food products.
  • pourable food products such as fruit juice, UHT (ultra-high-temperature treated) milk, wine, tomato sauce, etc.
  • UHT ultra-high-temperature treated milk
  • wine tomato sauce
  • etc. are sold in sealed packages made of sterilized packaging material.
  • Tetra Brik Aseptic registered trademark
  • a typical example of this type of package is the parallelepiped-shaped package for liquid or pourable food products known as Tetra Brik Aseptic (registered trademark), which is made by folding and sealing laminated strip packaging material.
  • the packaging material has a multilayer structure substantially comprising a base layer for stiffness and strength, which may comprise a layer of fibrous material, e.g. paper, or mineral-filled polypropylene material; and a number of layers of heat-seal plastic material, e.g. polyethylene film, covering both sides of the base layer.
  • a base layer for stiffness and strength may comprise a layer of fibrous material, e.g. paper, or mineral-filled polypropylene material; and a number of layers of heat-seal plastic material, e.g. polyethylene film, covering both sides of the base layer.
  • the packaging material also comprises a layer of gas- and light-barrier material, e.g. aluminium foil or ethyl vinyl alcohol (EVOH) film, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material forming the inner face of the package eventually contacting the food product.
  • gas- and light-barrier material e.g. aluminium foil or ethyl vinyl alcohol (EVOH) film
  • packages of this sort are produced on fully automatic packaging machines, on which a continuous tube is formed from the web-fed packaging material; the web of packaging material is sterilized on the packaging machine, e.g. by applying a chemical sterilizing agent, such as a hydrogen peroxide solution, which, once sterilization is completed, is removed from the surfaces of the packaging material, e.g. evaporated by heating; and the web of packaging material so sterilized is maintained in a closed, sterile environment, and is folded and sealed longitudinally to form a vertical tube.
  • a chemical sterilizing agent such as a hydrogen peroxide solution
  • the tube is filled with the sterilized or sterile-processed food product, and is sealed and subsequently cut along equally spaced cross sections to form pillow packs, which are then folded mechanically to form respective finished, e.g. substantially parallelepiped-shaped, packages.
  • the packaging material may be cut into blanks, which are formed into packages on forming spindles, and the packages are filled with the food product and sealed.
  • the so-called "gable-top” package known by the trade name Tetra Rex (registered trademark).
  • the above packages may undergo further processing, such as the application of a reclosable opening device.
  • the most commonly marketed opening devices comprise a frame defining a pour opening and fitted about a hole or a pierceable or removable portion of a top wall of the package; and a cap hinged or screwed to the frame, and which is removable to open the package.
  • a frame defining a pour opening and fitted about a hole or a pierceable or removable portion of a top wall of the package
  • a cap hinged or screwed to the frame, and which is removable to open the package.
  • other types of opening e.g. slide-open, devices are also known to be used.
  • the pierceable portion of the package may be defined, for example, by a so-called “prelaminated” hole, i.e. a hole formed in the base layer of the packaging material before covering the base layer with the layer of barrier material, which is therefore whole and closes the hole to ensure airtight, aseptic sealing, while still being easily pierceable.
  • prelaminated hole i.e. a hole formed in the base layer of the packaging material before covering the base layer with the layer of barrier material, which is therefore whole and closes the hole to ensure airtight, aseptic sealing, while still being easily pierceable.
  • the opening devices described, once formed, are normally applied directly to the packages by on-line application units located downstream from the packaging machine.
  • opening devices e.g. by heat sealing or gluing
  • application of the opening devices involves various preliminary operations on both the packages and the opening devices themselves. More specifically, when the opening devices are applied by heat sealing, both the heat-seal outer layer of the packaging material about the holes or pierceable portions of the packages and the opening devices are partly melted or softened locally by preheating.
  • the opening devices must be held firmly on the packages long enough for the contacting materials to cool and to permit adhesion.
  • one or both of the parts for gluing must be coated with adhesive, and the parts must be held firmly in contact with each other long enough to permit adhesion.
  • Application units which substantially comprise two, e.g. chain, conveyors for successively feeding the opening devices and the packages respectively along separate endless paths having respective adjacent parallel portions, along which each opening device is glued to the respective package.
  • application units are known, e.g. as described in Patent EP-A-1462370 , which comprise a first linear step conveyor for feeding a succession of packages along a first, preferably straight, path; a second linear step conveyor for feeding a succession of opening devices along a second straight path extending parallel and in the opposite direction to the first path; and a step-operated carousel conveyor for feeding the opening devices from a pickup station, coincident with one of the stop stations on the second conveyor, to an application station, where the opening devices are applied to the respective packages, and which coincides with one of the stop stations on the first conveyor.
  • the carousel conveyor feeds the opening devices along a circular path, with a vertical axis, through a number of intermediate work stations, where the opening devices are arrested and undergo various preliminary operations before being applied to the respective packages.
  • both known types of unit are extremely bulky, and have several parts that are accessible only with difficulty by the operator.
  • a modular unit for applying opening devices to packages of pourable food products comprising:
  • Numbers 1 and 1' in Figures 1 and 9 respectively indicate two possible configurations of a modular unit for applying two different types of opening devices 2 and 2' to respective sealed packages 3 of pourable food products.
  • Packages 3 are produced upstream from unit 1, 1' as described previously, from sheet packaging material comprising a base layer, e.g. of fibrous material such as cardboard, or of mineral-filled polypropylene material; and a number of layers of heat-seal plastic material, e.g. polyethylene film, covering both sides of the base layer.
  • the packaging material also comprises a layer of gas- and light-barrier material, e.g. aluminium foil or ethyl vinyl alcohol (EVOH) film, which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material forming the inner face of package 3 eventually contacting the food product.
  • gas- and light-barrier material e.g. aluminium foil or ethyl vinyl alcohol (EVOH) film
  • Each package 3 which is substantially parallelepiped-shaped in the example shown, has, on an end wall 4, an opening or a pierceable or removable portion (not shown), which is covered outwardly by a respective opening device 2, 2' applied to package 3 by relative unit 1, 1'.
  • opening devices 2 in Figures 1 , 2 , 3 , 4 , 6 and 7 are screw types made of plastic material, and each comprise in known manner an annular, externally threaded frame 5, which is fixed to wall 4 of a respective package 3 and defines a through opening 6 by which to pour out the food product; and an internally threaded cap 7 screwed to frame 5 to close opening 6.
  • Opening devices 2 may also comprise, in known manner, means (not shown) for piercing the pierceable portion or removing the removable portion of package 3 when unsealing the package.
  • Opening devices 2' in Figures 9 , 10 , 11 and 12 are flat, substantially rectangular, and hinged.
  • Each opening device 2' is made of plastic material and comprises in known manner a surrounding frame 5' (only shown partly) which is fixed to wall 4 of a respective package 3 and defines a through opening (not shown) by which to pour out the food product; and a cap 7' hinged to frame 5' to close said opening.
  • configuration 1 the modular unit according to the invention will first be described in detail with reference to configuration 1 only; configuration 1' will then be described solely insofar as it differs from configuration 1, and using the same reference numbers for parts identical or corresponding to parts already described.
  • unit 1 substantially comprises a supporting structure 15; a first linear conveyor 8, known and only shown schematically, for feeding a succession of opening devices 2 along a straight horizontal path P 1 ; a second linear conveyor 9, also known and only shown schematically, for feeding a succession of packages 3 along a straight horizontal path P 2 parallel and in the opposite direction to path P 1 in the example shown; and a transfer conveyor wheel 10 for feeding opening devices 2 from a pickup station 11 located along path P 1 , to an application station 12 located along path P 2 and for applying opening devices 2 to respective packages 3.
  • Supporting structure 15 comprises a substantially parallelepiped-shaped central body 16 defined by a number of parallel uprights 17 (only one shown in Figure 1 ) to which are fixed respectively a bottom beam system 31 and a top beam system 32.
  • Conveyor 8 is mounted on a supporting beam system 22 in turn fixed to top beam system 32 of central body 16, and defines, at least close to pickup station 11, a horizontal conveying surface 13, on which opening devices 2 are positioned with caps 7 downwards facing conveyor wheel 10.
  • Supporting beam system 22 is also fitted on top with an adhesive dispensing device 41 - in the example shown, for hot-melt glue - which acts on opening devices 2 as they travel along conveyor 8. More specifically, dispensing device 41 comprises a number of - in the example shown, three - dispensing guns 42 aligned parallel to path P 1 , and each having a respective nozzle 42a facing conveying surface 13 to feed adhesive onto a respective opening device 2. As they travel along path P 1 , opening devices 2 are coated with adhesive on the upward-facing side, i.e. the side opposite that facing conveyor wheel 10.
  • each dispensing gun 42 travels along a predetermined path to distribute adhesive onto the respective opening device 2.
  • Conveyor 9 is located below conveyor 8 and central body 16 of supporting structure 15, and defines, at least close to application station 12, a horizontal conveying surface 14, on which packages 3 stand with respective walls 4, to which opening devices 2 are eventually applied, positioned horizontally on top, facing conveyor wheel 10.
  • the spacing D 1 of opening devices 2 along conveyor 8 is different from, and more specifically smaller than, the spacing of D 2 of packages 3 along conveyor 9; the term "spacing" being used in the sense of the distance between corresponding points of two adjacent opening devices 2 or two adjacent packages 3.
  • conveyor wheel 10 is fixed to and projects from the front of central body 16 of supporting structure 15, and is therefore interposed between conveyors 8 and 9.
  • Conveyor wheel 10 rotates continuously about a horizontal axis A perpendicular to paths P 1 and P 2 , and feeds opening devices 2 along a curved path P 3 from pickup station 11 to application station 12.
  • Conveyor wheel 10 and central body 16 of supporting structure 15 together define a base module M 1 of unit 1; supporting beam system 22, conveyor 8, and dispensing device 41 together define a further module M 2 of unit 1 connectable to module M 1 as shown in Figure 1 ; and conveyor 9 defines a separate module M 3 connectable to module M 1 .
  • conveyor wheel 10 comprises a wheel 18 of axis A; and a number of gripping members 19 equally spaced about axis A and fitted to and projecting radially from wheel 18.
  • Unit 1 also comprises a number of connecting assemblies 20 for connecting respective gripping members 19 movably to wheel 18; and cam guide means 21 for altering the position of each gripping member 19 with respect to wheel 18 as wheel 18 rotates.
  • the spacing of opening devices 2 along path P 3 can thus be adjusted as required to adapt it to the requirements of specific operations to be performed on opening devices 2 (as explained in detail below), and to make it equal to spacing D 2 of packages 3 at application station 12.
  • connecting assemblies 20 comprise a number of guide members 23 extending radially about axis A and fixed to and projecting from an end surface 24 of wheel 18; and a number of slide members 25 fitted in sliding manner to respective guide members 23, and each supporting a respective gripping member 19.

  • Each gripping member 19 can therefore translate with respect to wheel 18 in a given radial direction with respect to axis A, and can oscillate with respect to wheel 18 about a respective axis B perpendicular to and incident with said radial direction.
  • guide means 21 comprise two curved fixed cams 27, 28 extending seamlessly about axis A and cooperating with respective idle cam follower rollers 29, 30 fitted to slide member 25 and plate 26, respectively, of connecting assembly 20 of each gripping member 19.
  • cams 27, 28 are defined by respective contoured grooves formed in a fixed vertical wall 33 located behind wheel 18 with reference to Figures 1 and 2 , or, more specifically, positioned facing an end surface of wheel 18 opposite end surface 24. All parts of cam 28 are located radially outwards of cam 27.
  • Cam 27 controls the radial position of gripping members 19 with respect to axis A as wheel 18 rotates, while cam 28 controls the orientation of gripping members 19, and therefore of opening devices 2, with respect to the radius of wheel 18 to which they are fixed.
  • gripping members 19, and therefore opening devices 2 change position with respect to wheel 18 as wheel 18 rotates, thus altering their peripheral speed.

  • Conveyor 8' is fitted to a supporting beam system 22' in turn fixable to top beam system 32 of central body 16 of supporting structure 15, in lieu of supporting beam system 22 and conveyor 8.
  • Coating roller 90 and the whole defined by supporting beam system 22' and conveyor 8' therefore define respective modules M 4 and M 5 connectable to module M 1 , in lieu of module M 2 , to define unit 1'.
  • Unit 1 is therefore substantially converted to unit 1' by substituting conveyor 8' for conveyor 8, installing coating roller 90 along path P 3 , in lieu of dispensing device 41 along path P 1 , replacing gripping members 19 with gripping members 19' designed to interact with opening devices 2', and replacing actuating mechanisms 60 with appropriate actuating mechanisms 60'.
  • each gripping member 19' substantially differs from relative gripping member 19 by comprising two movable jaws 91, 92 for gripping opposite sides of relative opening device 2'.
  • gripping member 19' comprises a substantially parallelepiped-shaped supporting body 93 which, like supporting body 56, is fixed to and projects from main portion 43 of relative fastening body 39, on the opposite side to that from which relative appendix 44 projects.
  • Jaws 91, 92 are defined by elongated bodies extending along opposite sides of supporting body 93, and comprising first end portions 94 adjacent to relative appendix 44 and hinged to supporting body 93 about respective axes D parallel to plate portion 37 of relative frame 34 and perpendicular to axis A; and opposite second end portions 95 located further outwards radially with respect to axis A, and substantially in the form of curved tips with their concavities facing to grip and retain a relative opening device 2'.
  • jaws 91, 92 are loaded elastically towards each other, to define a closed position, by a cylindrical helical spring 96 extending through supporting body 93 in a direction parallel to axis A.
  • End portions 94 of jaws 91, 92 define respective sector gears meshing with each other, and one of which (the one defined by jaw 91) is connected integrally to a lever arm 97 extending from relative axis D, in the opposite direction to relative jaw 91, and fitted with a cam follower roller 98 which cooperates in rolling manner with two fixed cams 66', identical with cams 66, to produce, at respective stations 11 and 12, a parting rotation movement of jaws 91, 92 about respective axes D into an open position enabling engagement and release of relative opening device 2'.
  • Unit 1' operates in exactly the same way as unit 1, the only difference being that opening devices 2' slide over, and are coated with adhesive by, coating roller 90 upstream from application station 12.
  • units 1, 1' are highly versatile and, with only minor alterations, can operate with different methods of applying adhesive to the opening devices (2, 2') and/or with different types of opening devices (2, 2').
  • units 1, 1' are characterized by comprising a common base module (M 1 ) to which can be connected different auxiliary modules (M 2 , M 3 , M 4 , M 5 ) designed for different types of opening devices 2, 2', and/or for performing different types of preliminary operations on opening devices 2, 2' prior to application to respective packages 3.
  • spacings D 1 and D 2 with which opening devices 2 and packages 3 are fed to wheel conveyor 10 are in no way dependent, and any necessary additional operations can be performed as opening devices 2, 2' are conveyed on conveyor wheel 10.
  • controlling the trajectory and speed of gripping members 19, 19' by means of cams 27, 28 minimizes impact between opening devices 2, 2' and relative gripping members 19, 19' at pickup station 11; for which purpose, the peripheral speed of gripping members 19, 19' at station 11 is preferably greater than the speed at which opening devices 2, 2' are fed to station 11.
  • opening devices 2, 2' may be heat sealed to respective packages 3, in which case, the adhesive coating operations would be replaced by heating operations performed, for example, upstream from wheel 18 or along path P 3 produced jointly by rotation of wheel 18 and the guiding action of cams 27, 28.
  • a heating module may easily be connected to base module M 1 to form, with only minor alterations, a heat-sealing unit for heat sealing opening devices 2, 2' to respective packages 3.
  • the unit according to the invention may operate with any combination of operations preparatory to applying the opening devices to the respective packages, and/or with any type of opening device.
